Y Application filed November 13, 1896. Serial No. 611,977. (No model.)

To a/ZZ whom it may concern:

Be it known that I, GUsTAF A. DAHLBERG, a subject of the King of Swedenand Norway, residing at New Sweden, in thel county of Nicollet and Stateof' Minnesota, have invented certain newl and useful Improvements inHand-Carts and I do declare the following to in section.

be a full, clear, and exact description of the invention, suchas willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thefigures of reference 'marked thereon, which form a part of thisspecification.

My invention relates to improvements in carts of the class usedespecially by farmers and gardeners and are provided with attachments bywhich they may be'converted into modified shapes, making them adaptablefor various kinds of work.

The objects of my invention are, first, to provide a twowheeledhand-cart which may carry a roll of fence-wire or a barrel or similarvessel for hauling water or anything else put into in; second, tolprovide a hand-cart which will automatically roll wire on and off itswire-reel by the motion ofthe cart and in rolling up the wire spreads iton the reel; third, to provide ahand-cart which may easily be convertedinto a horse-cart and drawn or pushed by a horse or mule These and otherminor objects I attain by the novel construction and arrangement ofparts illustrated in the accompanying drawings, vin which- Figure 1 is atop or plan view of my hand-cart with a`wire-reel mounted on it. Fig.4 2is a side view of Fig. 1 with one of the ground-Wheels removed. Fig. 3is a front view of one of the brackets 3. Fig. 4.is a left-hand sideview of Fig. 3. Fig. 5 is a perspective view of the frame-bar 4, whichin Fig. 1 is secured between the brackets 3. Fig. 6 is adetail frontview of a -portion of Fig; 1 with the pinion 19 Fig. 7 is a sectionalright-hand side view of Fig. 6, as on the line a, a, with the parts20and 21 left out and the brace 48 added. Fig. 8 is a rear end elevationof the cart as it appears when converted into a vessel-carrier forwater, &c.

Referring to the various parts in the drawings by reference-numerals, 1designates a pair of carrier-wheels or groundwheels which revolveuponthe journals 2, projecting outward from the two brackets 3, whichare secured together by the horizontal transverse frame-bar 4 and bolts5, passed through the flanges 6 of the brackets 7 of the frame-bar. Thebrackets 3 are further secured together by the arms 13and handle' 14,and the tube or hollow bar 8, passed through and being secured in thebrackets 3 by the pins 9, inserted through pipe and brackets, as shownin Fig. 1.

When the cart is used .with the barrel 10 on it, the bar 4 is removed,the frame in- Verted, as in Fig. 8, and the remaining transverseframe-bar 8 forms a support for the vessel 10, which is further held inplace by the side handles 11, secured on lit and embracing theprojections 12 of the brackets 3.

When the vessel is not needed, it is simply lifted out of the frame, thelatter returned to its normal position, and the cart is converted into afence-wire collector, carrier, and distributer, as will now bedescribed.

The pins 9 are removed from the brackets 3 and the wire-reel 16 securedby the pin 9X kupon the bar 8, which is therebyconverted into arevoluble shaft revolving in the brackets 3 and carrying theWire-reel'between the brackets, while beyond one of the brackets one ofits ends has secured to it a collar or clutch member 17 (see Fig. 6)with corrugations 18 upon its outer end, with which engages thecorrugated inner end of a loose collar 19, which is held in operativebut yielding contact with the collar 17 by the spring 20, to which moreor less tension may be given by the thumb-screwl 21, passing through thespring and being screwthreaded into the bracket 3. The loose collar ormember 19 of the friction-coupling thus formed is provided upon itsperiphery with sprocket-teeth 22, which engage a belt-chain 23, drivenby the sprocket-wheel 24, secured upon the innerv side of one of theground-wheels, so as to revolve with it and drive or revolve thewirereel.

The inner side of the sprocket-wheel 24 is provided with spiral-shapedgrooves or threads 25, engaging the teeth 26 of a horizontally-placedcog-wheel 27, revolving on a stud-28, secured in the bracket 29,projecting almost horizontally from the frame-bar 4, to which it issecured at 30. (See Fig. 5.)

To the bar 4 is further pivoted at 31 the horizontally-swinging arm 32,which is connected by the pitman 33 to the crank-pin 34, secured in thewheel 27. The free end of the arm 32 is formed with a head 35, carryingfour friction-rollers 3G, 37, 38, and 39, between which the wire 40 isguided olf and onto the reel.

The spring 2O has its upper end held in position by a cavity 41 (shownin Fig. 6) inthe center of the pinion 19.

42 is a pawl pivoted at 43 to one of the frame arms or brackets 3 andengages normally the ratchet-teeth 44, provided upon the circumferenceof the clutch member 17, thereby preventing the reel from unrolling thewire when the latter is to be stretched by the cart. Then it is desiredto liberate the reel from the pawl, the latter is swung out ofengagement with the ratchet-teeth and kept in that position by theengagement of the spring 45 with the projection4 46 near the front endof the pawl.

The arms or shafts 13 are pivoted at 47 to the brackets 3 and arefurther braced thereto by the oblique braces 43,pivoted at 49 to theshaft and at 50 to the bracket 3. The end of the brace pivoted to thebracket is provided with a series of holes 51 52 53, by which the bracemay be shortened or lengthened, thereby regulating the height of theshafts 13 and handle 14 to any desired or convenient position.

lVhen it is desired to move the cart by horse-power, the detachableshafts 54 are secured by bolts, as 55, to the main shafts 13, as shownin dotted lines in Figs. 1 and 2, and the tugs of the harness aresecured in the holes 57 of the detachable shafts.

In operation it has already been stated and shown in Fig. 8 how the cartis used as a Water cart or carrier in general and how it is differentlyrigged as a wire-cart. It will be further observed that when the cart ismoved either by hand-power or horse-power the ground-wheel secured tothe spiral-grooved wheel 25 causes the latter to revolve, Whereby thechain belt 23 Adrives the wire-reel 16, thereby winding upon it the wirein taking down fence-wires, dto. Should the reel re- .volve too fast forthe motion of the cart,

I use a certain kind of reel for the cart; but common reels of variouslengths on which the fence-wire is sold in the market may be used, whenso desired, and the stroke of the arm 32 may then be regulated by movingthe crank-pin 34 into the various holes 26X in the wheel 27. When thecart is to be changed to a water or vessel carrier, the spring 20 issprung with its upper end out of the cavity in the clutch member 19,swung on the screw 21 out of the Way for the shaft 8, which is then,after being released from the reel by removing the pin 9X, pulled out ofthe brackets 3 and returned after removing the reel, the clutch member19, and the spring 20. The removal of the frame-bar 4, the inverting ofthe frame, and placing of the vessel have already been described.

What I claim as new, and desire to secure by Letters Patent, is-

1. A combined hand and horse cart, having detachable shafts for thehorse, adapted to be readily attached to the shafts used for handpower,substantially as set forth.

2. In a wire-cart, the combination with a pair of ground-wheels, axleand frame carried thereby, a wire-reel mounted on the frame andoperatively connected with one of the ground-wheels, a shunting-leverpivoted in the frame and carrying at one end rollers for guiding thewire onto the reel, a pitman pivoted to said lever, the crank-wheel 27operating the pitman and having teeth upon its periphery and aspiral-toothed wheel engaging said teeth, and being secured vto one ofthe traction-wheels, is thereby revolved, and operates theshunting-lever, substantially as set forth.

3. In a hand-cart the combination of a pair of ground-wheels, a framecarried thereby, a wire-reel mounted inthe frame and a swinging arm forguiding the wire onto the reel, said arm being provided with fourfrictionrollers or guiding-sheaves between which the wire passes, andmeans for swinging the arm by the revolving of one of the ground-wheels,substantially as shown and described.

4. A hand-cart having a pair of groundwheels and a frame carriedthereby, and a pair of shafts projecting from the frame and connectedtogether by a handle as 14, said shafts being adjustably secured to theframe, so that they may readily be raised and lowered relatively to theframe, by the extensible braces 4S, substantially as and for the purposedescribed.

In testimony whereof I affix my signature in presence of two witnesses.
